ROJAS HERNANDEZ, J.A.; GONZALEZ PEREZ, M.G.; FLORES VILCHEZ, F.  e  SOTO FELIX, M.. Soil urbanization in watersheds in the metropolis of Guadalajara, Mexico: entropy by surface runoff. Revista bio ciencias [online]. 2022, vol.9, e1246.  Epub 12-Abr-2024. ISSN 2007-3380.  https://doi.org/10.15741/revbio.09.e1246.

To consider the current scenarios in terms of urbanization, sectorial decision-making, and implementation of urban-territorial intervention plans and programs, the edaphological and hydrological conditions of the Colomos-Atemajac sub-basin in the metropolis of Guadalajara, Mexico were contrasted for the periods of 2008 and 2022, to determine the variation of the volume of water flow and its relationship with the urbanization process and the increase of impermeable areas. Data obtained in situ were processed in the Qgis geographic information system; in addition, standardized equations and methods in hydrology were used to calculate all parameters for the elaboration of precipitation hydrographs. It was found that in 2008 there were 8.44 km2 of a low-density residential area, and by 2022, said value decreased to 5.56 km2; giving transition to a higher residential density, with an increase of 2.89 km2. The information obtained was conceptualized from the Entropy-Homeostasis-Negentropy systemic model; an extended derivation of the Pressure-State-Response model of the Organization for Economic Cooperation and Development. In conclusion, the current hydraulic infrastructure does not satisfy the stream flow regimes and surface runoff exceeds the retention and transport capacity; as a result, floods annually affect not only the same urban areas but also new areas that have replaced their soil cover.
